| 摘 要： | 以甲醛、丙酮和乙二胺为原料，经过Mannieh反应合成了曼尼希碱酸化缓蚀剂YZ-1。通过正交实验得出最佳合成条件为：反应温度70℃，反应时间4h，酮醛胺摩尔比为2：2：1，HCl加量1．0％。用静态失重法在不同温度、不同加量以及不同酸液类型及酸液浓度下，对其缓蚀性能进行了综合评价。结果表明，缓蚀剂YZ-1在盐酸、氢氟酸和土酸中均有良好的缓蚀效果，其耐温性高达150℃，是一种很好的高温酸化缓蚀剂。 |

| Abstract: | A Mannich- base acidification inhibitor YZ -1 was synthesized by Mannich reaction with formaldehyde, acetone and ethylencdlamine as the raw materials. By orthogonally designed experiments,the optimal synthetic conditions were found as follows： Reaction temperature 70℃, the reaction time 4 hours, acetone, formaldehyde and ethylenediamine molar ratio 2： 2： 1, HCl dosage 1.0%. The performance of corrosion inhibitor YZ - 1 was evaluated by zero - gravity test at different temperatures, different inhibitor concentrations and types and different concentrations of acids. The result indicated that Corrosion Inhibitor YZ - 1 in hydrochloric acid, hydrofluoric acid and acid soil exhibited good inhibition performance. It can tolerate a temperature up to 150℃ and is a good high- temperature acid corrosion inhibitor. |
